validation

You may not bother with html validation or writing simple and clean code when designing your web site. Later you may find your site is slow loading, appears incorrectly in the main browsers and does not rank well for the major search engines.

Validating the html and other codes in your website can be a time consuming task. Because validation simply checks the mark up language for proper syntax, some have wondered if using this process will benefit a site when it comes to search engine rankings, and as such, is it worth doing?

Form validation on the client-side is essential - it saves time and bandwidth; you also have better control to show the user the wrong field. This comparison of different validation methods includes comments for improving portability and maintainability.

Code validation is still widely debated as to whether it is required for performance within the search engines. It is only a guess that the search engines don't utilise it within their algorithm, but nobody is actually 100% sure on that fact. Tests are performed and results obtained with conflicting information whether code validation is taken into account. What's new and interesting though, is the overwhelming popularity of XHTML.

Eavesdropping attacks are often easy to launch, but most people don't worry about them in their applications. Instead, they tend to worry about what malicious things can be done to the machine on which the application is running. Most people are far more worried about active attacks than they are about passive attacks.

Your website is ready. Your content is in place, you have optimized your pages. What is the last thing you should do before uploading your hard work? Validate. It is surprising how many people do not validate the source code of their web pages before putting them online.
